Project-based learning can significantly enhance critical thinking skills in candidates preparing for the UPSC. By engaging in practical projects, learners apply theoretical knowledge to real-world situations, driving analytical thinking and problem-solving. This mode of learning encourages collaboration, as students often work in groups, which exposes them to diverse perspectives and ideas. Such interactions stimulate questioning and creativity. Additionally, project-based learning allows students to explore subjects in depth, fostering a sense of ownership over their education, which not only aids in information retention but also prepares them for the complexities they will face in civil service roles.
